Why didn't he reply to my message?

I think his attitude towards you now is a skeptical attitude. . It feels like you're dating someone else and you don't like him very much. That's why I won't accept him and let him wait like this. . The first sentence you sent him. This shows your attitude. Don't let him be your boyfriend . He suspected that you were going on a date, and now you said you wouldn't let him be a boyfriend. . No wonder he is happy. . .
